I gave 'Revolutionary' a spin today. Track #2 - Bach: "Evolutionary" Toccata and Fugue in D Minor - is downright scary with its bass extension & the length of time that these notes are held.

While my M2s handled the mids & highs with ease, I thought that my little EP400 was going to cough its woofer out onto the floor; however, it made it through OK!

The dynamics of this SACD are amazing, from the softest, almost inaudible keyboard notes to the sudden blasts of the big foot pedal notes. I can't imagine what a really big system must sound like on this track...

Unless one has a very robust system, I wouldn't play this one at excessive levels. Woofer damage is certainly possible if there isn't some kind of limiting involved.

I suspect that I was playing it at about an average of 85 Db. Unlike when I was far younger, once the volume gets higher than that, I have to back it down as I just don't enjoy these high levels anymore. Besides, my house & my 4 cats just can't take it either, ha!

I've heard numerous pipe organs in cathedrals & while they are impressive & powerful they don't generate these sound levels within their huge structures that we can in our smaller areas.
